Abstract EN
Significant consequences result when a microgrid is connected to a distribution system.
This study discusses the impacts of bolted three-phase faults and bolted single line-to-ground faults on the protection coordination of a distribution system connected by a microgrid which operates in utility-only mode or in grid-connected mode.
The power system simulation software is used to build the test system.
The linear programming method is applied to optimize the coordination of relays, and the relays coordination simulation software is used to verify if the coordination time intervals (CTIs) of the primary/backup relay pairs are adequate.
In addition, this study also proposes a relays protection coordination strategy when the microgrid operates in islanding mode during a utility power outage.
Because conventional CO/LCO relays are not capable of detecting high impedance fault, intelligent electrical device (IED) combined with wavelet transformer and neural network is proposed to accurately detect high impedance fault and identify the fault phase.
